implemented by the OPGD or ETHB board.
NE Convergence
The MA5680T/MA5683T features powerful access and convergence capability. In the
downstream direction, it supports cascading to other devices through the GE or 10GE port. In
the upstream direction, it supports connection to the IP/MPLS network through the GE or 10GE
port. It also supports dual homing to the BRAS through direct connection.
Unique ATM DSLAM Cascading Function
The MA5680T/MA5683T supports cascaded ATM DSLAM devices and finally migrates the
ATM convergence network to the Ethernet convergence network.
l The MA5680T/MA5683T can inherit all the ATM services, including the ATM STM-1
port, PPPoA/IPoA, and high speed Internet (HSI) line services.
l The MA5680T/MA5683T supports the IPoA and PPPoA access services on the subscriber
side, which are converted into the IPoE and PPPoE modes inside the device and then
accessed to the IP network.
l The MA5680T/MA5683T supports upstream transmission in the Ethernet, ATM PWE3,
or ETH PWE3 mode.
